1.)Let U = {1,2,3,4,5,6,7,a,b,c,d,e} X = {1,7,d,c,e} Y = {1,3,4,a,c} Z = {1,5,a,b,e} a.) Find Xu(Ynz) b.) Find X'Z' 2.) Denote the set by using the listing method: the set of all odd positive counting numbers. 3.) Use a Venn diagram to shade the set: A'B 4.) Find the value of n(AUB) if n(A) = 12, n(B) = 14, and n(AB)=5.
